Re: How do you determine "at the lands" by your method?
Very wise words from BountyHunter. Buy the tools he states and follow the prescribed steps and you can't go wrong. The only other thing I'd add that I didn't see (maybe it is in there somewhere) is to make sure your sizing die is centered and adjusted correctly. I had a forster sizing die with the split lock ring and occasionally the die would be slighty crooked after tightenning the ring, thus causing runout. Me personally, I just took a ring off an RCBS die and after twisting the sizing die firmly onto the shell holder to allign it, I would tighten the lock ring. No more problems with run-out. I am a big fan of forster inline seating dies (regular bench rest dies). They are the father of the redding inline dies which came out as soon as the patent on the forster dies run out. You pay quite a bit more for the redding mic dies than you do for the forster dies. Personally, I don't use the mic dies. Also, the configuration of the seating plug in the forster (as well as for the redding) acceptsmany more low drag bullets than do RCBS (built off speer bullets) plugs and hornady plugs.
